Hello, I am new to Fenics. Suppose:
from dolfin import * mesh = UnitSquareMesh(4, 4) V = FunctionSpace(mesh, "Lagrange", 1) def boundary(x): return x < DOLFIN_EPS or x > 1.0 - DOLFIN_EPS
There should be 8 ‘line’ elements on both side and I want to supply an array of 8 numbers to set the boundary condition. How shall I achieve this? I only know that supplying an expression would work but haven’t googled anything about supplying an arbitrary vector/matrix.
Thanks in advance!
